3×3 · top 3.1% of 284,439 all-time · competing since December 2014 · 2014JOYE01
Yeon Ha Jo has been competing for 12 years. His best event is the 3×3: a personal-best single of 8.20, set at 3x3x3 HanMaDang 2017, puts him in the top 3.1% of the 284,439 people who have ever been ranked in the event, and 198th in Republic of Korea. Until July 2008, no official 3×3 solve in the world had been that fast. Across 5 competitions since December 2014, he has put 78 official solves on the record across four events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 9 counted rounds. His 3×3 best has come down from 11.23 in December 2014 to 8.20, a 27% improvement. Yeon has entered five competitions, more competitions than 83% of everyone who has ever competed.

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
